Concepts ​

Reliza Hub ​

Reliza Hub is a service that provides a single view for all key DevOps activities in the organization. This includes Projects (or Components), Bundles, Instances.

Further, Reliza Hub allows to control what software should be deployed on what instance and also allows to provision ephemeral instances with desired bundles.

Project (or Component) ​

Project refers to software that is being developed and usually maps to a version control system repository (i.e., Git repository). In other words, if you are working on a software which has its own Version Control repository or is a component in a Monorepo - that would be a Project.

Developers usually think in terms of Projects when discussing their work.

Branch ​

Branch is a part of the Project and usually has same meaning as a branch in a version control system branch (i.e., Git).

Usually branches are divided into Base branch (main), Feature branches (short-term) and Release branches (long-term). In practical sense, Feature branches, usually have different naming and versioning conventions, i.e. they can be named after tasks like feature/ticket-2.

Bundle (or Products) ​

Bundle is a customer-facing, operational piece of software. Bundles are not mapped directly to a version control repository, but rather through their components. Components of Bundles are either Projects or other Bundles.

Customers, project managers and product marketing teams usually think in terms of Bundles (frequently referred to as Products) when describing software produced by organization.

Using Bundles-Project combination helps communication between Development, Ops and Product Marketing teams.

Feature Set ​

Feature Set is a part of the Bundle. It is understood as specific set of functionality as to be delivered to the customer. Feature Set for a Bundle is what a Branch is for a Project.

Artifact ​

Artifact may be a binary resource, container image or a collection of directories and/or files. We support artifact types as per CycloneDX specification of Component Object resource - currently using CycloneDX schema v1.4.

We assume that 2 Artifacts are equal if they are of the same type and their known hashes or digests (such as sha256 or sha512) are equal.

Source Code Entry ​

Source Code Entry is a pointer to specific commit or revision in a version control system. Unlike commit in a distributed VCS, Source Code Entry also points to specific central VCS repository to ensure auditability.

Release ​

Release may belong to a Project or a Bundle.

In the case of a Project Release, Release points to a specific Source Code Entry and may have several Artifacts. It may also have any number of components (other Releases).

In the case of a Bundle Release, Release would only have components (other Releases) and may have only auxiliary artifacts (i.e., test reports related to this release).

Instance ​

Instance is a medium which runs software built by organization (Projects or Bundles). This could be a VM, a set of VMs, a Kubernetes cluster, a PaaS solution - literally anything that is configured to run software. Instance is defined by its URI.

Application ​

Application is a logical organization of a group of projects and bundles. Approvals are scoped to Application. Particularly, each application may have its own approval policy for the same environment type.
